没有jquery的平滑滚动条（鼠标滚动）？答案

【问题标题】：Smooth scroll bar (on mouse scroll) without jquery?没有jquery的平滑滚动条（鼠标滚动）？
【发布时间】：2018-02-02 02:57:03
【问题描述】：

我想在滚动页面时实现平滑，例如这个站点link 具有我正在谈论的效果。我实现了单击时的滚动动画，但我想在用户使用 mousewheel 滚动时实现平滑滚动。我正在寻找没有 jquery 的解决方案。（这不是 stackoverflow 中任何问题的重复）。

【问题讨论】：

Smooth scroll anchor links WITHOUT jQuery的可能重复
没有。不希望仅在单击时滚动。我想在用户使用鼠标滚轮滚动时平滑滚动效果
@george B，我不建议更改默认滚动行为。有很多图书馆可以做到这一点，但大多数用户都注意到了这一点，并可能导致令人沮丧的体验。查找“scrolljacking”以获取更多信息。
半年后，但也许这对某人有用。这实际上可以使用 javascript 轻松完成，请查看stackoverflow.com/questions/7408100/…（可能重复）。尽管我同意 Phix 的观点，这对最终用户来说确实是一种令人沮丧的体验，但我不认为轻微的改变是坏事。我真正认为不好的做法是固定滚动限制了部分之间的移动
